Abstract
To facilitate the development of better underwater communications technology, a sea trial was carried out in the Bedford Basin (NS, Canada) in the summer of 2014. Modems were used to send messages and coincident ambient noise measurements were recorded. The ambient noise data were analyzed in order to verify the signal to noise ratios of the equipment and to investigate the characteristics of the Bedford Basin noise during this time. Specifically, the ambient noise power spectra were compared to two existing ambient noise models. The model-data agreement for each comparison varies significantly by time of day and frequency band. In general, the Merklinger-Stockhausen model was more accurate than an extension of the wind-noise part of the APL-UW model. However, there were fairly large discrepancies between the model and data even on an averaged basis.
